The LTC

1562-2 is a low noise, low distortion continuous

time filter with rail-to-rail inputs and outputs, optimized for a

center frequency (f

) of 20kHz to 300kHz. Unlike most

monolithic filters, no clock is needed. Four independent 2nd

order filter blocks can be cascaded in any combination, such

as one 8th order or two 4th order filters. Each block’s

response is programmed with three external resistors for

center frequency, Q and gain, using simple design formulas.

Each 2nd order block provides lowpass and bandpass out-

puts. Highpass response is available if an external capacitor

replaces one of the resistors. Allpass, notch and elliptic

responses can also be realized.

The LTC1562-2 is designed for applications where dynamic

range is important. For example, by cascading 2nd order

sections in pairs, the user can configure the IC as a dual 4th

order Butterworth lowpass filter with 90dB signal-to-noise

ratio from a single 5V power supply. Low level signals can

exploit the built-in gain capability of the LTC1562-2. Varying

the gain of a section can achieve a dynamic range as high as

114dB with a

±5V

supply.

Other cutoff frequency ranges can be provided upon request.
